Ya, your numbers are about the same as mine, so you may be hosed. I'm predicting my 4th bar dropping in Sept/Oct 2018 (maybe it will make it to spring). However, with 33,000 mi, you've got a lot of extra miles. Unless located in very high temperature areas, most people aren't losing the 4th bar until >45,000 mi (some not even at all, or just over 60,000). Your best chance is to accelerate your mileage use, use the DCQC, charge to 100%, and drive lots of highway speeds with high acceleration/deceleration. Remember, the motor can take energy out of the battery faster than the Chademo DCQC. Also, the Nissan warranty is that the car will always provide FULL acceleration (no loss of functionality). You can ALWAYS do this without voiding the warranty. This is their downfall because full acc is something like 4C (vs 2C for Chademo DCQC) and will really heat up the battery! I wish I'd realized this earlier.

You've got more than 8000 mi/mo, 250 mi/day. You might as well enjoy them. :twisted:

Yeah, no quick charge on my Leaf and not sure I can get 250 miles out of it on a day. Level 2 charge only from my home. Thanks for the suggestions, I'll just try my best to wear down the battery as much as possible. Leaf Spy should have been purchased when I bought the used Leaf but hindsight is always 20/20.

Thanks again for all the suggestions. May all the leaves run without any issues!

Thanks for the additional numbers, looks like your battery numbers are good. No chance of a warranty replacement for you.

The leaf is great, thanks Nissan for a car without many issues other than battery degradation.

Any other 2013 Leaf Spy stats anyone else can share with manufacture date January 2013 through March 2013?

Thanks for all the forum help. I wish I was on this forum a year ago! I am glad I made the move to own a Nissan Leaf. Teslas are a money pit...

It looks like my 5/2013 built Leaf is now getting really close to losing 1 bar. I did the best I could to keep it out of high temps during the summer. I generally succeeded on work days (e.g. got it into an area that stayed below 80 F even on 90+ F ambient temp days and always kept it out of the sun). I also left my car outside for several hours each night to cool before driving it into my garage at home.

I'm surprised it hasn't happened already as I've not seen SOH this low nor Hx down to 80.xx% before.

As of earlier this evening (11/20/17)
AHr: 54.86
SOH: 83%
Hx: 80.77%
odo: 49,563 miles

I figured it'd happen soon after SOH hit 84% back on 11/15, but I guess not.

your stats are VERY good for a 3/13 build. Several have had much worse with the general consensus that "4/13" packs and later having much more durability.

As far as parking in Sun, keep SOC lower as much as possible and that will help. Other than that, your car's interior will be well over 100º but not sure the interior temps play that much of a role on the battery temps. Your driveway composition maybe the the important variable. White concrete will have less radiant heat over black asphalt.

Just broke 40,000 miles a few weeks ago myself and know I am on borrowed time as well. I have not looked at my LS stats in about 4 months. Guess I don't want to know how close to the edge I am. Put new ecopia+ tires on a couple months ago and took a good hit on mileage since then. I've got about 4500 miles on them now and have recovered a little bit since, but I can tell my range is not where it used to be with them.

Funny thing, when the cooler weather arrived recently, I readjusted my PSI up to 45 (it was at 37). It feels like I went backwards in range since then. I'm temped to drop them back down and track the change since my drive is pretty static and consistent.

I work in Livemore, so I could not avoid the heat while parking, but did park in the shade on those 95+ days. I park in the garage when home unless temps overnight were significantly cooler outside. I still charge to 100% every workday and usually never get below 25%.

I'll be sure to update the thread when that 1st bar drops.

I finally lost my 1st bar tonight on 11/21/17.

I know in the morning I had all 12 bars. I'm pretty sure I left work w/all 12 bars. I stopped to get something to eat on the way home and when I powered up, 1 bar was gone. Upon connecting w/Leaf Spy my stats w/the bar gone were:
(Leaf Spy's SOC: 64.9%)
AHr: 54.88
SOH: 83%
Hx: 80.83%
odo: 49,598 miles
0 QCs (this car doesn't have a CHAdeMO inlet)
3212 L1/L2s (I use the charging timers with the 80% midnight to midnight trick virtually every workday so I know this count is way inflated due to its quirks. If I charge at home (rare), I usually use a timer since I'm on a TOU plan and also want to limit the amount of time spent at 100% charge.)

viewtopic.php?p=430825#p430825 had this car's stats when I bought it used in July 2015. Carfax and Autocheck say my car was manufactured 5/23/13. Carfax says my vehicle was first "sold" on 6/22/13.

Anyone here have an '11 or '12 Leaf in the South Bay part of the SF Bay Area have/had a build month 4 to 6 in 2011 or 2012? If so, at about what mileage and vehicle age did your first bar go?

If nobody gets to it, I'll try to add myself and a few other bar losers (esp. some of the 30 kWh ones) sometime between this weekend and end of year to http://www.electricvehiclewiki.com/Real ... acity_Loss.

My 2014 S just lost its first bar yesterday. I only bought it a month ago, great timing on the seller's part! Will have to check LeafSpy & report back with some Hx/SoH numbers. 30,700 miles on the car, which was sold originally in Georgia then came to southern California, so it has seen some fairly warm summers.

Living in NorCal Bay Area, very nice cool temperatures. We see about seven or less 100F degrees days in a year. The battery temperature has almost always been in the 5 range and only saw it a few times on 6 in summers and start the day off with 4 bars on most winter days. Always parked and charge the car overnight after 12AM and end charge before 6AM in the cooler temperatures. The cars day begins around 8AM and ends by 7:30PM.Daily commute use of about 35 miles a day and weekend probably another 40 miles. Always driven carefully no problems with the car so far. All battery tests at Nissan came out to be perfect.

This is what the free version of Leaf Spy showing
May 25th 2014 delivery
32,254 miles (probably happened into last 100 odd miles.
AHr= 56.02
SOH= 85%
Hx= 83.36%
383.72V -.083A
8 QCs
1549 L1/L2 - So about 800 Charges (timer use) : Mainly using 240V 12A, 16A or 27A

Current SOC = 67.4% Temperatures outside are about 55F and the after a 6 mile drive the Temperature sensors are all showing 63 -61F range.
Also I was getting 4.6 miles/KwHr till I changed my tires 6000 miles ago and it went down to 4.0 miles/KwHr with new tires. Now it has slowly climbed to about 4.3 miles/KwHr.

I am not very clear with all the above Leaf Spy battery specific terms and still trying to learn them.
Do these look normal?? Based on all the reading on the forums, It seems a bit early to me.

Any thoughts?? :( :(
